The article considers the features of the gasometric survey and seismic exploring results on the regional geophysic profile in territory of the large geostructual blocks on south-eastern part of Russian platform: Voronezh anticlise, Rjazano-Saratov’s deflection and Zhiguljov-Pugachov deflection. It selected testes of gas from 2m depth there are metan, its gomologes, hydrogen, gelium. In gas anomalies the fractured tectonic and geostructured elements reflected. Its presents the oil-gas prospecting interest.

In the article practice complex methods is considered at working off of regional geophysical profiles, the necessity rational complex geophysical and geochemical methods for the purpose of direct forecasting of oil and gas deposits is proved and the model of joint interpretation of the received data is offered

Thorough lithologic investigations were used as the basis to demonstrate integration of the epigenetic transformations in the rocks from the transitional complex and the mantle of the West Siberian Plate in the process of tectono-hydrothermal activation.

Certain tendencies are supposed to show up in morphogenesis of the Late Cretaceous skeletal sponges, hexactinellids; those tendencies make it possible to distinguish some forms of diverse-level modular organization among the unitary representatives of the group. Generation of primitive ≪modular≫ forms, defined as the perifrontal ones, is associated with incomplete gemmation and isolation of solitary cross canals, apo- or prosochetes

Based on new finds of mandibular tooth plates of the chimaeroid Stoilodon aenigma Nessov &Averianov, 1996 (Holocephali, Chimaeroidei) from the Lower Cretaceous of central Russia, the diagnosis of the genus is modified and validity of the taxon is confirmed. New record of mandibular plate of the species from the Ryazanian regional stage (boreal Berriasian stage) of the Moscow Region has allowed us to expand stratigraphical distribution of the species within the whole early Cretaceous. It is estimated that Stoilodon did not exceed 1.5 m in body length.

The article discusses some features of hydrothermal alteration of basaltic amygdaloidal Turin volcanogenic-sedimentary series. The composition and the relationship of mineral components performing tonsil. The alternation of layer silicates and zeolites, indicating a change in the composition and physico-chemical characteristics of the mineral solution.

The condition of the natural monument “open-cast Zaplatinovka” in territory of Saratov in the condition of anthropogenous loading is considered in the article. The characteristic of a cut of anthropogenous deposits is resulted, stages of transformation of s relief on a site are allocated

Assessment of textural and structural varieties of rock salt can make a prediction texture characteristics of reservoir rock salt for possible use in the design and construction of underground storage tanks

Lithologies were examined of the cores from the deep wells that have penetrated the entire section of the Triassic system in the Pricaspian Depression; material compositions and accumulation peculiarities of the Triassic sequences have been revealed. Certain events have been found comparable to those in the North Germanic Depression.

Tasmanites Newton green algae are suggested as marine sediments scattered organic matter catagenetic maturity indicators. Indicator palynological scale of rock maturation determination and its application were are regarded based on regular variation of cyst membrane with the increase of temperature

A layer characterized by the ostracod genus Paraparchites species formation outbreak exists in the Lower Permian Kungurian stage section of the Urals, Precaspian basin and northern part of the Caspian Sea. This layer is regarded as a Paraparchites biofacies, which has a certain place in the lateral series of sedimentation environments. Commercial hydrocarbon accumulations are associated with it within the northern flatbed zone of the Precaspian basin.

Results of ekologo-geochemical approbation in territory of preschool institutions of a city of Engels are presented. The data about disease of children in the given establishments on various types of diseases is analysed. The estimation of an ecological condition of a soil cover is given

The Precaspian depression subsoil geothermal mode characteristics result not only from presence of the huge evaporite formations and salt dome tectonics, but also from the depth structure of its no granite crust and underlying lithospheric mantle. The current heat flow is primarily of mantle origin and correlates with the HC, helium and other mobile components deep fluid flow.

Explorations of 1979–1982 and 2006–2009 have made the field ready for industrial development and have revealed peculiar manifestations of internal salt tectonics within the subhorizontal halogenic bodies. The degree and the character of intrasalt tectonics are estimated according to boudinage, i. e. the response of the rigid dolomite- anhydrite interlayers within the salts to arising tectonic stresses. Upon folding, the interlayers are torn into separate fragments and stretched along the bedding.

Event stratification of the sections constitutes an investigation trend aimed at detailed interregional correlation of sedimentary sequences. Based on extensive factual material, the authors have revealed the most significant changes in the Middle Triassic sedimentary and volcanogenic-sedimentary bodies. The entire Middle Triassic is peculiar for manifestations of hydrothermal-metasomatic processes within terrigenous, biogenic, volcanogenic bodies and bodies of mixed origins.

The following sequence from the Kamennyj gully (Volgograd Region) has been shown to occur in the section, upwards from below: a sand member as the lower portion of the Late Bajocian alluvial Gnilushkinskaya suite; the upper (clayey) part of the overlying littoral Karaulinskaya suite, referred to the Upper Bajocian Pseudocosmoceras michalskii biozone; fragments of a complete section of the Lower Bathonian Zhirnovskaya suite (Gonolkites convergens zone), with the clays deposited under the normal shallow sea conditions; the upper part of the Middle Bathonian Kamenno-Ovrazhna

Arterial directions in formation of module organization of skeleton hexactinellids are caused by vegetative forms of reproduction. It is supposed that some tendency of selection of protozoa module forms can be traced in morphogenesis of separate generic types of late Cretaceous sponges. The concept “polyosculumic„ sponges is considered in vast context personally in reference to skeletons with some osculumics formed in the result of partial regeneration of organism

Considered the results of ecological and geochemical soil sampling and made the estimate of dusting in the ≪Volskcement≫ cement producing plant affection zone (the city of Volsk, Saratov region), which is the city-forming company and also the main source of environmental impact

Analysis of the published material has made it possible to show the cyclic variations of the earth’s response to be practically coincident with the orbit parameter fluctuations, when the time lag of 5–6 thousand years is considered. In the earth’s response, however, periodicity changes are more complicated due to resonance phenomena and to numerous feedbacks in the system responsible for additional period occurrences.

In 1960–1980, the Elton and the Gremyachka deposits of potassium salts were discovered within the Permian halogen sequences in the Lower Volga Region, bischofite presence was recorded in the Privolzhskaya monocline, the conditions of halogen-bed formation were defined as those peculiar for typical evaporites. But in 1980-2010, halogenesis hypotheses emerged that denied the principal importance of climatic factor and the dominant role of oceanic waters in the brine composition of the salt-generating basin.
